S. Army Corps of Engineers' report <br />regarding the footbridge under construction downstream <br />from Ski Hill Road in Breckenridge. <br /> <br />Considering the characteristics of the channel in this area, <br />it is reasonable to expect an adequately engineered bridge could <br />have abutments that encroach into the Blue River Channel and <br />still pass 100-year flood flows without significantly affecting <br />the flood elevations. <br /> <br />without bridge design drawings and without performing a hydraulic <br />analysis of the new structure, we can not comment any more <br />specifically. <br /> <br />Sincerely, <br /> <br />GINGERY ASSOCIATES, INC. <br /> <br />Patrick F.
